The teacher asked a question: take a complete deck of playing cards, remove the king and Xiao Wang, face up, and people draw a playing card from it. Is the equivalent of J.

Take a complete deck of playing cards (there are 54 cards). Remove the king Xiao Wang (there are 52 others). J*** has four. But the equivalence of j is: 4/52 =113. K also has 4 pieces. The possibility of making walnut K is:113. 13 of a deck of playing cards are spades. The possibility is: 13/52= 1/4. There are 26 black cards, and the possibility is 26/52 = 65438+.
